SPINDLE-SUPPORT FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent 1\To.350,038I dated September 28, 1886.

(No model.)

To all whom, t may concern:

Be :it known that I, EDGAR J CARROLL, of Vorcester, county of lVorcester, and State of Massachusetts, haveinvented an Improvement in Spindle-Supports for Spinning-Machines, of which the followingdescription, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide simple and efficient spindle-supports for use in connection with what are known as top l spindles, or spindles having but one bearing and that at the lower end, the object being to enable the spindle-support to move freely to a limited extent in any direction as the lower end of the spindle is made to vibrate by means of high speed or unequal loading, and this without the employment of a bolster held loosely in a bolster-case, as now commonly done.

In this my invention the splndlesnpport, composed of a foot having a rigid upright sleeve to receive the pintle of and furnish the only lateral support for the spindle, is connected loosely to a base, a dovetail groove in one receiving a correspondingly-shaped keel of the other, the keel litt-ing the said groove loosely.

Figure l shows a sleeve-whirl spindle supported in accordance with the invention herein to be described, all the parts, except the spindle, which is shown in elevation, being shown in section; and Fig. 2 is a vertical section of my improved spindle-support at right angles to the section of Fig. .1, the sleeve-whirl spindle being omitted.

The bolster-railR receives the bolt B, having the head b provided with the keel b. (Shown as of dovetail shape.) rIhe keel b enters loosely a correspondingly-shaped groove in the foot f of the bolster, consisting of a block, F, having a solid upright sleeve or tube, f in which is placed the pintle p of the sleevewhirl spindle S, the spaceqbetween the keel and the groove in the foot of the bolster being of Sudicient size to permit slight movement in any direction of the bolster with the lower end of the spindle when the latter is in practical use. The nut Nholds the bolt B in place upon the 5o rail lt.

In another application filed concurrently herewith, Serial No. 205,882, I have shown a bolt having a round hole in its head and a bolster with a round hole in its foot for the reception of a stud or pin, and such is not therefore herein claimed. Herein there isa sort of a tongne-and-groove connection between the foot of the bolster and the head ol' the bolt.

I do not intend to limit my invention lo the exact construction orshape of the keel shown, and instead thereof may make the said keel of any well-known equivalent shape in crosssection.

It is obvious that the keel might be on the foot and the groove in the head of the bolt without departing from my invention.

I claiin- The combination, substantially as described, 7o with a sleeve-whirl spindle and a bolster composed of a block having a solid sleeve to receive the pintleof the spindle and a foot, of a bolt having ahead, the head and foot being loosely connected one with the other by a keel, substantially as described, one entering a groove made in the other, whereby the spindlesupport is enabled to move to a limited extent in any direction with the lower end of the spindle.

In testimony whereof I. have signed my name to this specification in the presence of two subscribing witnesses.

EDGAR J. CARROLL.
